How do we build and model our databases?

At sustamize, we model all CO₂-equivalent values using a transparent and scientifically robust methodology. To ensure accuracy and international comparability, all greenhouse gases are converted into CO₂e in line with the Kyoto Protocol and the IPCC Assessment Reports. This conversion is based on the corresponding Global Warming Potentials (GWP) for each gas, which are fully integrated into the sustamize databases.

Our datasets are built using a bottom-up modeling approach, similar to a process flow. Each data point is grounded in qualified sources, including peer-reviewed LCA studies, industry publications, scientific datasets, and standardized environmental reports. This ensures that our data remains consistent, traceable, and aligned with globally recognized standards such as the GHG Protocol and ISO 14067.

To guarantee the highest level of quality and reliability, the calculation methodology across all sustamize databases is independently validated by GUTcert GmbH. Please find here the certification.
